Abstract
In a bending region in a frame region, a slit is formed in at least one inorganic film included in a TFT layer extending through the inorganic film and exposing an upper surface of a second resin film of a resin substrate layer, and at least one opening is formed in an inorganic insulating film of the resin substrate layer in the bending region. In the opening, a first resin film and the second resin film are in contact with one another.
Claims18
A display device, comprising:
- a resin substrate including a first resin film, an inorganic insulating film, and a second resin film layered in this order;
- a light-emitting element included in a display region, the light-emitting element being provided over the resin substrate with a TFT layer in between;
- a frame region provided around the display region;
- a terminal portion provided at an end portion of the frame region;
- a bending region provided between the display region and the terminal portion;
- at least one inorganic film provided in the frame region and included in the TFT layer layered on a surface of the resin substrate;
- a frame flattening film provided covering the inorganic film on the surface of the resin substrate;
- and
- frame wiring lines connected to the light-emitting element and extending to the terminal portion, the frame wiring lines being provided on a surface of the inorganic film and a surface of the frame flattening film,
- wherein in the bending portion, a slit is formed in the inorganic film extending through the inorganic film and exposing an upper surface of the second resin film of the resin substrate,
- at least one opening is formed in the inorganic insulating film of the resin substrate in the bending region, and
- the first resin film and the second resin film are in contact with one another in the opening.
